Assigns the contents of that to *this.

1,2) `tagged` has defaulted copy and move assignment operators that invoke the corresponding assignment operator of `Base`.
3) Converting move assignment from a different `tagged` specialization with matching tags. Equivalent to static_cast<Base&>(*this) = static_cast<Other&&>(that);.
4) Converting copy assignment from a different `tagged` specialization with matching tags. Equivalent to static_cast<Base&>(*this) = static_cast<const Other&>(that);.
5) Assigns that to the `Base` subobject. Equivalent to static_cast<Base&>(*this) = std::forward<U>(that);.

### Return value

*this.
